The Green Lantern oath comes from DC's Green Lantern comics, where members of the Green Lantern Corps recite it as a pledge before using their power rings. The lines about brightest day and blackest night have become one of the most recognisable superhero pledges in comics and animation, and fans often re-record or remix it for their own edits. This RWBY-linked version offers a cleaner second take, making it easier to drop into fan videos, cosplay clips and crossover edits without distracting noise getting in the way.
